I got a logitech quickcamera usb a couple of months ago, and I still haven't been able to get it to work quite right. I let a friend borrow it for her laptop and it worked perfectly. She is running windows 98, I am running windows xp. The problem is that after a couple of minutes, the screen goes black, and i cant take a picture or record video, and the only way to get it to work again, is to restart my computer. I installed the latest software from logitech that came out this month. I have Abit K7vt motherboard, and i have the latest via patches and stuff. Ive tried it in my various usb ports and ive tried the pci latency patches and nothing seems to help at all. All my drivers are up to date. Any help would be greatly appriciated bc i am out of ideas.
